6803-2RS Ceramic Bearing 17x26x5 Stainless Steel Sealed ABEC-3 Ball Bearings IMI Brand

This 6803-2RS 17x26x5-millimeter sealed ball bearing is a single-row bearing for supporting typical radial loads. Its stainless steel construction makes it resistant to corrosion and high temperatures and it conforms to ABEC 3 precision standard for performance within a narrow range of variation. The rubber seals on both sides of the bearing keep lubricant in and contaminants out. This single-row sealed ball bearing is for use in applications that involve combined radial and axial loads and a need for high running accuracy at high rotational speeds. Such applications include clutches, drives, gearboxes, compressors, pumps, turbines, and printing and textile machines, among others.

Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
